Difference Between Intrinsic Semiconductor & Extrinsic Semiconductor

March 19, 2019 By admin

Fermi level for P-type Semiconductor

A conductor has a number of charge carriers, which are ready to take part in conduction after a certain voltage or heat is applied. Non-conductors do not have any free charges to take part in conduction even after applying an external voltage or heat. The materials which exhibit properties of both conductors and non-conductors are called semiconductors. The Semiconductor materials behave as an insulator for a certain voltage level and conduct only after the specific voltage level is applied at … [Read more...]

What is Intrinsic Semiconductor and Extrinsic Semiconductor – Energy Band & Doping?

P-type semiconductor with acceptor impurity

Semiconductor, as the name suggests is a kind of material whose shows properties of both conductors and insulators. A semiconductor material requires a certain level of voltage or heat to release its carriers for conduction. These semiconductors are classified as ‘intrinsic’ and ‘extrinsic’ based on the number of carriers. The intrinsic carrier is the purest form of semiconductor and an equal number of electrons (negative charge carriers) and holes (positive charge carriers). The semiconductor … [Read more...]
